1 Claim. (Cl. 305-9) This invention relates to apparatus for snowremoval and more particularly is directed to an apparatus of a tractionconstruction, including actual snow removal devices which areadjustable.

An object of this invention is to provide a combined snow plowing deviceand a traction device, whereby the snow plow may be adjusted to removesnow from the path of the traction device, but leaving suflicient snowin the path pursued by the traction device so that additional sledspulled by the traction device can easily transverse along the path.

Another object of this invention is to provide a self contained snowremoving apparatus comprising snow plow, adjustable and hingedly mountedwith respect to a traction device, with the traction device including atraction unit including separable traction belts and a pair of tractionrollers arranged between the belts and at the forward position of thetraction device. Mounted above the traction belts and to the rear of therollers is an enclosed cabin for accommodating various items such as theoperators cab, fuel tank, prime mover, etc.

The operation of the device as referred to in the foregoing contemplatesovercoming many of the hazardous conditions usually found in communitieswhere the snow fall is extremely heavy and where the distribution anddisposal of supplies is of paramount importance. Therefore it iscontemplated to provide a snow removal and traction device which may beused to progress through heavily snowed in areas, hilly and otherwise.The snow plow itself may be adjusted to remove a goodly amount of snowbut leaving a suflicient amount for providing easy travel, in a welldefined path, for supply sleds drawn by the traction device itself. Theplow is adjustable to push the snow to both sides in the conventionalmanner, or maybe adjusted to push the snow either to one side or theother. The importance of providing a device which may push the snow awayon either side lies in the fact, that if the device is proceeding overhilly country or where the contour of the country is such that steepascents or traverse along the side of a hill becomes necessary, the plowmay be adjusted to push the snow downwardly and away and not directlyforward of the traction device as it is proceeding, for instance, up ahill. The purpose of the device is usefully served when the snow is soheavy that a large amount of snow may be removed to permit the tractiondevice pulling supply trains to crawl through the path left by the plow.The front rollers, which revolve in the forward position only of thetraction device, have the utility to scale banks or obstructions, andleave a level road for the supply train.

With the above and other objects in view which will appear as thedescription proceeds, the invention consists of the novel construction,adaptation, combination and arrangement of parts hereinafter describedand claimed. These objects are accomplished by devices illustrated inthe accompanying drawings wherein:

2,702,212 Patented Feb. 15, 1955 Referring to the drawings, throughoutwhich like reference numerals indicate like parts, the numeral 10designates the apparatus as a whole and comprises the assembled tractiondevice 11, the plow 12, and a part of a supply sled 13.

The traction device includes a pair of traction belts 14 disposed overand around pulleys or wheels 15, mounted on shafts 16, journalled in achassis 17. Each of the wheels 15 has teeth 18 arranged in spacedrelation on their periphery, for engagement with equally spaced toothlike members 19 on the inside surface of the traction belts 14.

The chassis 17 comprises side members 20 joined by end member 21 at therear, and raised at 22 at the forward ends at a substantial angle withrespect to the rear side members 20. lntegrally formed with side members20 are a plurality of depending flange members 23 which are perforatedto receive the shafts 16 with the forward ends at 22 provided with otherflange members 24 also perforated to receive similar shafts 16. It willbe noticed that the flanges 24 are much smaller than flanges 23 forconstructional purposes.

An enlarged wheel or roller 25 is rotatably mounted on a shaft 26connecting the forward ends 22 over which the belts 14 pass with aroller 27 of similar size mounted on a shaft 28, connecting the members20 adjacent the end member 21. A third roller 29 of larger diametersthan any of the previously mentioned wheels or rollers is mounted onshaft 30 which also connects the members 20 at approximately the pointwhere the ends 22 are disposed upwardly at an angle.

Attention is directed to the fact that all of these rollers are providedwith spaced toothed portions along their periphery for cooperating withthe sections 19 in the belts.

A flange 31 of substantial size is formed integral with each member 20adjacent the base of members 22, and are apertured for receiving shafts32 upon which a pair of idler rollers 33 are mounted.

The shaft 28 provides space for including a driving connection for thedrive belt 34 which is connected to the pulley 35 mounted on shaft 36 ofa prime mover, not shown.

The extreme ends of members 22 are provided with glPPOItS 37 upon whichare rotatably mounted pulleys Heavy coil springs 39 are strategicallyspaced intermediate the chassis 17 and a body 40. These springs may restin any suitable supports 41 of sufficient size to retain the base of thesprings.

Thebody 40 is enclosed and because of the nature of use of the devicemay be of sufficient size to include an operators cab 42, seat 43,actuating lever 44, heater 45, bed 46, fuel tank 47, and motor room 48.

A pair of pulleys 49 are supported on protruding member 50 secured tothe front of the body cab with a pair of pulley members 51 secured tosupports 52 attached to the bottom of the body in a forward position.

Extending outwardly and forwardly from members 22 are longitudinal arms53, a pair of which are each hingedly mounted on each member 22 and havetheir free ends equipped with supports 54 which in turn support the plow12.

The plow 12 comprises two independent and separable sections designatedby the numerals 55 and 55 having their centrally disposed ends at onecorner hingedly mounted at 56 and having their adjacent ends so arrangedthat upon hinged movement these centrally disposed ends are scissorlikein operation. A plate 57 is disposed over the top of the hinged section56 so that regardless of the hinged movement, the opening, resultingfrom the movement of the sections 55 and 55' will always remain covered.

Secured to each section 55 and 55' and hingedly mounted thereon are arms58 and 58' respectfully having their free ends 59 and 59' respectivelyfree to engage brackets 60 and 60 when in the position as shown inFigure 4 or arranged to engage the end support 61 which in turn isconnected to the sections 55 and 55' of the plow 12 and incidently forma mount for the supports 54.

When it is desired to arrange the plow 12 to assume the position ofFigure 5, the free end 59 of arm 58 is swiveled in the bracket 60 andused as a lever to push section 55 outwardly on its hinged end wherebythe free end 59 is temporarily locked in a bracket 62, one end of whichis secured to end support 61. When it is desired to arrange the plow 12to assume the position of Figure 6, the free end 59' instead of 59 ofarm 58, is swiveled in the bracket 60 and used as a lever to pushsection 55 outwardly on its hinged end whereby the free end 59' istemporarily locked in a bracket 62', one end of which is secured to endsupport 61.

Plow adjusting cables 63 are secured to the top of each section 55 and55' at points designated as 64 and 64. Each cable is drawn over a pulley38 and a roller 49, pulley 51 and extends to a point near the rear ofbody 40 where it may be connected to the operating mechanism associatedwith the prime mover. Essentially the manner of exerting or lesseningtension on the cables is solely for the purpose of raising or loweringthe plow 12 vertically, to adjust the height of the plow with respect tothe belts 14 for the purpose of removing snow but leaving a sufiicientamount for the belts 14 and supply sled 13 to transverse over easily andwithout undue obstruction.

Referring to Figure 3 it will be noticed that belts 14 are spaced by apair of circular front sections 65 which only serve to fill out thespace between the belts 14 and have tractor threads similar to thoseappearing on the outside surface of belts 14. These sections 65 revolvein the front area only and are independent of the chassis 17 and members22 and 20.

The cab 42 includes the usual windshield 66 and window 67. Included alsoin the body 40 is a stove 68.

The supply sled 13 may be connected to the tractor through the medium ofcoupling devices 69 and 70 joined together by a cable or bar 71. Anexhaust vent 72 may be disposed immediately above the motor room 48.

In operation, the plow 12, or more specifically, the sections 55 or 55'may be arranged as illustrated in Figures 4, or 6, dependent upon thecontour of the region over which the tractor is moving and as explainedheretofore in the specification. The operator in the cab may raise theplow 12 to any desired levelby actuating the mechanism for drawing thecables and then through the prime mover 48, drive belt 34 and toothedwheel 27 cause movement of the tractor belts 14.

It will thus be seen that there is provided a device for snow removaland tractor device in which the several objects of this invention areachieved. and which is well adapted to meet the conditions of practicaluse.

As various possible embodiments might be made of the above invention,and as various changes might be made in the embodiments set forth, it isto be understood that all matter herein set forth or shown in theaccompanying drawings is to be interpreted as illustrative and not in alimiting sense.

Having thus described my invention, what I claim and desire to secure byLetters Patent of the United States is:
